The attached patch contains mostly trivial changes, including a few
spelling corrections, plus changes to the types of condition raised in
various cases. The only significant change, I believe, is

  - MAKE-DISPATCH-MACRO-CHARACTER no longer raises an error if the
    character already was defined to be a macro character; it
    overrides the previous definition (as per a suggestion from Drew
    McDermott on cmucl-help, dated 2002-09-22).

o Fix a few typos in code.
o Delete a few unused symbols from various places
o Use something better than %%RWSEQ-EOF%% for the eof marker.
o Add target-foreign-linkage vars for the PPC and HPPA ports to aid
  cross-compilation.  (The values are very likely wrong, but they're
  not used yet.)

Based on a larger patch from Eric Marsden.

The idea of using of MACROLET instead of SYMBOL-MACROLET is due to
Bill Newman, and Christophe Rhodes made it work in SBCL.


  * prevent SYMBOL-MACROLET from binding special variables, as per
    CLtS. This requires a change to the (rather ugly) way that the
    assembler uses symbol-macrolet on two special variables that
    contain the current segment and the current vop. We encapsulate
    all accesses to the special variables by macros, and replace the
    symbol-macrolet machinery by a macrolet.

broke the SPARC port.

Patch to correct non-ANSI use of symbol-macrolet in compiler backend.
Also fix symbol-macrolet to disallow binding to special variables.

Take out :reads/:writes since :dependencies is now used.
Add to the instruction generator code for collecting dynamic statistics if
needed.
Accept :cost from the instructions file for instruction costs.

for mappings, use ssets and simple-vectors.  In define-instruction, have
one piece of code that computes both the read and write dependencies at once
instead of having two difference pieces of code that build lists of each.

sure that the last value written is the last value written.

before, but now I think I do.  Make INSERT-EMITTABLE-INST skip branches,
because they get handled explicity in SCHEDULE-PENDING-INSTRUCTIONS.  Fixed
SCHEDULE-PENDING-INSTRUCTIONS to guarantee that instructions that depend on
the branch will be emitting in the branch delay slot.

Changed several #+nil's to #+debugs so that we can selectivly turn debugging

Also print the INST-EMITTER when printing instruction structures so we can tell
what the instruction is.

TN-LOCATION to convert TNs into locations.  Actually call EMIT-NOP instead
of just printing a message that a nop needs to be inserted.

When using adjust-array to extent the vector of output-blocks, spec the

emitter function uses the inst macro to emit instructions that normally
want to be back-patched.

a nested use of ASSEMBLE and have variable scoped in the outside ASSEMBLE.
Also, only bind *current-segment* and *current-vop* if they were supplied.

Added a :vop-var option to DEFINE-INSTRUCTION so you can use the assemble
(and inst) macro inside instruction emitters.

Fixed DEFINE-INSTRUCTION-MACRO to enter the expander under the symbol's
name instead of the symbol itself, because that is what we look for.
